A mobile device experiences a condition where a time overlap exists between a packet data burst being communicated over a packet data channel of a serving cell and broadcast data burst being communicated over a broadcast control channel of a neighbor cell. The mobile device sets its RF receiver to receive the packet data burst instead of the broadcast data burst based on identifying that the neighbor cell is not a candidate for an upcoming handoff. On the other hand, the mobile device sets its RF receiver to receive the broadcast data burst instead of the packet data burst based on identifying that the neighbor cell is a candidate for an upcoming handoff. The mobile device may set the RF receiver to receive the packet data burst instead of the broadcast data burst based on further identifying that a call drop is imminent.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for a mobile device having a radio frequency (RF) receiver for wireless communications, the method comprising: producing, by the mobile device, scheduling data of the mobile device; scheduling the RF receiver of the mobile device based on the scheduling data, the scheduling comprising prioritizing a packet data burst being communicated to the mobile device over a packet data channel of a serving cell over a broadcast data burst being communicated to the mobile device over a broadcast control channel of a neighbor cell when the neighbor cell is not a candidate for an upcoming handoff; setting an RF transceiver to receive an initial portion of the packet data burst in response to identifying that the neighbor cell is a candidate for an upcoming handoff and that a call drop between the mobile device and the serving cell is imminent; and controlling an RF transmitter of the mobile device to cancel an uplink packet data burst if the uplink packet data burst would overlap in time with the broadcast data burst and the device identifies that the neighbor cell is a candidate for an upcoming handoff and that a call drop between the mobile device and the serving cell is imminent.
2. The method of claim 1 , wherein setting the RF transceiver to receive an initial portion of the packet data burst comprises reducing a number of slots to be received.
3. The method of claim 1 wherein identifying that the call drop is imminent by identifying when a signal strength measurement of the serving cell is below a predetermined threshold.
4. The method of claim 1 further comprising: receiving and decoding, at the mobile device, a plurality of packet data bursts over a packet data channel of the serving cell; and while receiving and decoding the packet data bursts over the packet data channel of the serving cell, receiving and decoding, at the mobile device, a plurality of broadcast data bursts over the broadcast control channel of a neighbor cell.
5. The method of claim 1 wherein the packet data channel comprises a packet data traffic channel (PDTCH) and the broadcast control channel comprises a broadcast control channel (BCCH).
6. The method of claim 1 wherein the broadcast control channel is defined by a first frequency and time slot combination and the packet data channel is defined by a second frequency and time slot combination.
7. A mobile communication device comprising: a radio frequency (RF) transceiver; a controller coupled to the RF transceiver; the controller being configured to: produce, by the mobile device, scheduling data of the mobile device; schedule the RF receiver of the mobile device based on the scheduling data, the scheduling comprising prioritizing a packet data burst being communicated to the mobile device over a packet data channel of a serving cell over a broadcast data burst being communicated to the mobile device over a broadcast control channel of a neighbor cell when the neighbor cell is not a candidate for an upcoming handoff; set the RF transceiver to receive an initial portion of the packet data burst in response to identifying that the neighbor cell is a candidate for an upcoming handoff and that a call drop between the mobile device and the serving cell is imminent; and cancel an uplink packet data burst if the uplink packet data burst would overlap in time with the broadcast data burst and the device identifies that the neighbor cell is a candidate for an upcoming handoff and that a call drop between the mobile device and the serving cell is imminent.
8. The mobile communication device of claim 7 , wherein setting the RF transceiver to receive an initial portion of the packet data burst comprises reducing a number of slots to be received.
9. The mobile communication device of claim 7 wherein the device identifies that the call drop is imminent when a signal strength measurement of the serving cell is identified to be below a predetermined threshold.
10. The mobile communication device of claim 7 wherein the controller is further configured to: receive and decode a plurality of packet data bursts over a packet data channel of the serving cell; and while receiving and decoding the packet data bursts over the packet data channel of the serving cell, receive and decode a plurality of broadcast data bursts over the broadcast control channel of a neighbor cell.
11. The mobile communication device of claim 7 wherein the packet data channel comprises a packet data traffic channel (PDTCH) and the broadcast control channel comprises a broadcast control channel (BCCH).
12. The mobile communication device of claim 7 wherein the broadcast control channel is defined by a first frequency and time slot combination and the packet data channel is defined by a second frequency and time slot combination.
13. A non-transitory computer readable medium comprising computer instructions stored in the non-transitory computer readable medium, the computer instructions being executable by one or more processors of a mobile communication device having a radio frequency (RF) receiver to cause the device to: produce, by the mobile device, scheduling data of the mobile device; schedule the RF receiver of the mobile device based on the scheduling data, the scheduling comprising prioritizing a packet data burst being communicated to the mobile device over a packet data channel of a serving cell over a broadcast data burst being communicated to the mobile device over a broadcast control channel of a neighbor cell when the neighbor cell is not a candidate for an upcoming handoff; set the RF transceiver to receive an initial portion of the packet data burst in response to identifying that the neighbor cell is a candidate for an upcoming handoff and that a call drop between the mobile device and the serving cell is imminent; and cancel an uplink packet data burst if the uplink packet data burst would overlap in time with the broadcast data burst and the device identifies that the neighbor cell is a candidate for an upcoming handoff and that a call drop between the mobile device and the serving cell is imminent.
14. The non-transitory computer readable medium of claim 13 , wherein setting the RF transceiver to receive an initial portion of the packet data burst comprises reducing a number of slots to be received.
15. The non-transitory computer readable medium of claim 13 further comprising computer instructions to identify that the call drop is imminent by identifying when a signal strength measurement of the serving cell is below a predetermined threshold.
16. The non-transitory computer readable medium of claim 13 wherein the computer instructions are further executable to cause the device to: receive and decode, at the mobile device, a plurality of packet data bursts over a packet data channel of the serving cell; and while receiving and decoding the packet data bursts over the packet data channel of the serving cell, receive and decode, at the mobile device, a plurality of broadcast data bursts over the broadcast control channel of a neighbor cell.
17. The non-transitory computer readable medium of claim 13 wherein the packet data channel comprises a packet data traffic channel (PDTCH) and the broadcast control channel comprises a broadcast control channel (BCCH).
18. The non-transitory computer readable medium of claim 13 wherein the broadcast control channel is defined by a first frequency and time slot combination and the packet data channel is defined by a second frequency and time slot combination.
